Since my engine broke, I had to remove the valves to check for bent valves. I got to inspect the heads.
I had filled the exhaust crossovers with aluminium. I used a Hi-temp adhesive/putty to fine tune the exhaust bowls, because my aluminium shrunk slightly after the pour. This stuff was easy to work with, and it is holding up so far. I bought a 4 oz tube, and I used about half of it do do both heads. I forget what I paid for it, I think it was about $26.00, but I am not sure. Also if I remember correctly, I plugged "RESBOND 907" into a search engine, and it located a company in NC, which sells if by the tube. WWW.COTRONICS.COM (712) 646-7996 Good luck and happy racing...

It is ok if the aluminum sits down in the crossover as it really doesn't effect intake flow or exhaust flow. I would be worried that putty would break away...if it does it could nick your valve seat or worse.

Yes .5", it is still where I put it. I even put some in the end exhaust bowls, I created ramps on the uphill side of the guides

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
